Abstract

The soils studied are situated in the northern part of Gardno-Łebsko Lowland, which is part of the Słupsk Plain. For laboratory research two parcels were chosen, with the area of 0.5 ha, situated in protected district of Smołdziński Las. The research of the selected parcels shows great differences in the construction of soil and flora profiles. What they have in common is the high level of groundwater, which is influenced by slight changes during the vegetation season. The investigated soils have the acid reaction in all parts of their profile. The lowest values observed in levels of moulder differed from 3.56 to 3.74 pH_H20.

Key words: forest ecosystem, soil, flora, ground water, organic carbon
